Babysitting with an Angel

Chapter One

Kimberly wasn't ready for this. She currently stood gaping at Dean, who looked about three and held a baby in his arms. That baby was Sam, just as he used to be when he was about eight months old. Perfect. Then there was three year old Crowley standing there holding the hand of a smaller girl who looked about two. Meg. Great.

Kimberly was twenty-eight, rather like her mother in appearance with the same stunning smile her father and Dean had. She had Sam's brown eyes, Dean's bravery and loyalty with Sam's compassion all rolled into one. She was strong and brave, but she was terrified as she gazed at the children before her, who, however long, would rely on her and Castiel for protection, love and care.

"Gabriel..." Castiel sighed, "What have you done?"

The Apocalypse had been over for a mere three weeks, and all of that time had been made up of Castiel and Kimberly trying to work on their relationship. The Winchesters had bought a house to live in, Gabriel, Bobby and Crowley stopping by whenever possible, with the occasional visit from Meg. Castiel stood looking at the young woman who knelt before the children, Dean and Crowley looking at her with big tearful eyes.

"It's okay..." She promised, noticing the look on their faces that told her they recognised her, "It's Kimberly..."

"Kimmy?" Dean asked, Kimberly nodding and smiling at the nickname.

"Yeah, honey," She said sweetly, "It's Kimmy."

Dean stepped forward and pressed into her arms, sniffling and showing her Sam who lay there with his gorgeous brown eyes, gazing up at her and blinking a few times and smiling sweetly. He let out a soft sound and reached out with tiny hands, Kimberly smiling down at him. He was so beautiful, as Dean was, and even Meg and Crowley. She didn't know how long they'd be this way and she looked to Castiel, her eyes showing how helpless she felt. He knelt beside her, Dean gasping and scowling at the angel.

"You no touch my Sammy!" He huffed, Kimberly sitting on the floor properly and kissing Dean's head.

"It's alright, Dean. It's only Cas, and he's not going to hurt your brother." She promised, "Can I hold Sam?"

Dean, who was holding his brother protectively, watched Castiel carefully who raised an eyebrow as he passed Sam over, the little boy sniffling and murmuring in her arms before he kicked his legs.

"Hey, beautiful..." She whispered, smiling as Sam yawned and wriggled the slightest bit, "Bet you're tired, huh?"

Great. She was left in the house with an angel who'd never cared for a child in his life with and four children, one being a baby and the other three being toddlers.

"Cas, we're gonna need some toys and things." She began, the angel sighing in response.

"I see..." Castiel replied, "What things?"

"Toys, as I said..." She said softly, "Diapers, clothes, a crib, changing things...a stroller..."

The angel looked confused and Kimberly sighed.

"Could you call Bobby for me?"

Bobby to the rescue! He'd been out, bless his cottons and bought the children everything they needed, but he was still hunting, which meant he had to go back on the road, leaving Kimberly with Castiel and the children. Castiel was currently sat with Meg and Crowley, clueless as to what he had to do, while Dean snuggled into Kimberly's side and watching as the woman rocked a crying Sam to sleep. He had a pacifier on a string around his neck and she took it off, removing the pacifier from the string and passing it to Castiel before placing the pacifier in Sam's mouth.

"Good boy." She said sweetly, kissing his head gently, "Sleep now, baby."

Sam's cries eased as Kimberly began to sing gently to him, everyone looking at her as she did, even Crowley and Meg.

"I heard there was a secret chord
That David played and it pleased the Lord...
But you don't really care for music do you?"

Castiel smiled as Crowley and Meg shuffled closer to him, snuggling into his sides as Dean did to Kimberly, Sam's eyes blinking slowly as he began to fall asleep. Kimberly was a lovely singer and a great carer for the children that had been thrust into their care. Castiel knew that someday she'd make a wonderful mother, and he hoped that perhaps the two of them could start their own family when all this was over.

"It goes like this: The fourth the fifth,
A minor fall and a major lift,
The baffled king composing hallelujah...
Hallelujah, hallelujah...
Hallelujah, hallelujah..."

Sam was asleep, as was Dean, and Meg...and Crowley. Yes, Kimberly was definitely a wonderful carer.

Crowley mumbled and rolled over in the spare bed, Meg by his side with Dean on the other side, all of them wriggling a little in their sleep. Castiel smiled at the children and stroked their heads, unable to stop himself pressing kisses to their temples and tucking them in once more.

"Goodnight, little ones." He whispered, turning on the baby monitor just in case before closing the baby gate and heading into the room he shared with Kimberly.

She'd been busy setting the equipment up while he cared for the children, the angel amazed at how handy she was around the house. Now, she was in Sam's room, looking over into his crib before kissing his head and checking all the wards and sigils in the room.

"Goodnight, honey-bear..." She whispered, Sam cuddling his teddy to him as he slept peacefully in the crib, "I love you, baby boy..."

Castiel hid in their room, watching as Kimberly opened the door to the other bedroom to say goodnight.

"Night, sweethearts," She whispered, "I love you..."

With that, she closed the door and entered the bedroom, finding Castiel already in bed waiting for her, wearing nothing but his boxers.

"Hey," She said softly, climbing into bed beside him and kissing his lips, "You okay?"

"Hello, Kim..." Castiel replied, kissing Kimberly's lips in return, "I'm fine thank you. Are you alright?"

"I'm fine, sweetheart," She said sweetly, "Just fine."

The young woman sighed and curled up to Castiel, the bedroom lights being turned out by a click of the angel's fingers as they settled together in the bed they shared. Kimberly rested against Castiel's chest and turned on both baby monitors, one labelled S for Sam and CMD for Crowley, Meg and Dean.

"I just wanna keep a check on them," She whispered, Castiel kissing her head and smiling, "I'd hate for anything to happen to them."

And that's when soft sobbing came from one of the baby monitors, the rustling of sheets before a little voice sounded through both monitor and the corridor outside the bedroom.

"Kimmy!"

It was Meg, crying her little eyes out and presumably standing at the baby gate. The child had barely made a fuss, but now she sounded so upset it made both Castiel and Kimberly's chests hurt.

"Kimmy! Me wee-weed!"

Kimberly grimaced and bit her lip, kissing Castiel's lips before climbing out of bed and heading to the child, opening the baby gate and lifting her up into her arms.

"Shhh," She soothed, "It's alright, Meg...let's get you cleaned up, okay?"

The little girl whimpered and rested against Kimberly who grabbed a pull-up diaper and some clean pyjamas before carrying Meg to the bathroom to clean her up.

However long Gabriel had put this spell on the children for, Kimberly knew that for both her and Castiel, it was going to be tough, but she didn't know it would be one of the most amazing experiences of their lives.
